Still another `object oi the inventionis. toj provide for insulation as to heat and Coldwan respect to both tile and metal .types of'roong ele-V ments, and in the case of metal roofing elements to provide for insulation as to sound.

Another object of the present invention is to provide a roof construction which is particularly adapted for use in combination with metal building frames. In this respect resilient metallic channels for receiving and supporting the tile'or metal roofing elements, are welded to 'the metal frame of the building so that the frame and channel members mutually reinforce each other with the result that the building frame and the roof body incorporate a high degree of mechanical strength.

With the above and other ends in View the invention is more fully disclosed with reference to the accompanying drawing, in which Fig. 1 is a plan View of a metallic shingle;

Figs. 2 and 3 are sections taken on the' lines 2--2 and 3--3 of Fig. 1, respectively;

Fig. 4 is a perspective of a detail; Fig. 5 is an assembly view in side elevation of i the shingles on a roof, and

` Fig. 6 is a view shown in cross section taken along the line 6-6 of Fig. 5. Referring to the drawing by character of reference the numeral 50 designates a substantially rectangular metallic shingle formed at one end 4 with a downturned flange 5I for abutment by one end of a sheet of insulating and sound deadening material 54 which may be bonded or otherwise suitably secured to the underside of the metallic shingle. The shingle 50 may be formed of sheet metal and is provided with a pair of downturned spaced resilient iianges 52 which are formed out of the shingle 'and extend longitudinally thereof, 5o the flanges 52 being formed along their lower edges with outwardly facing grooves or elongated sockets 53. The insulating or sound deadening material 54, which may be tar paper or other suitable material is pierced by the depend- 55ing flanges 52, the insulating material being in 'the extended portion 59 snaps into the grooves 52 sheet form and tapering longitudinally of the shingle.

The numeral 51 designates la roofing structure to be covered by the shingles 50 and secured to this structure in any suitable manner is a plu- 5 rality of spaced substantially U-shaped holders 55 for the shingles. Each holder comprises a base 56 which may be rigidly secured to the roof structure 51 `in any suitable mannerrand extending upwardly from` the base are spaced` resilient 10 `ilanges 58 provided adjacent their upper ends withf inwardly directly elongated extended portions 59 which seat in the `grooves 52 to resiliently holdthe shingles in place.

In mounting the shingles on the roof it is only 15 necessary to position the resilient anges 52 of a shingle between the upturned iianges 58 of a holder and rpress the shingle into place or until `of the holder.

- In order to avoid metallic contact between ad jacent or overlapping shingles the insulating material 54 extends below or beyond the lower edges of the abutment flange 5I asV shown in Fig.` 5. Also the holders 55 are relatively spaced, such 25 that the shingles 50 overlap, the upper overlapping end portions of the shingles being pressed `fragment of a` channel shaped retainer'fora tile roong element (not shown) the retainer having means providing an abutment for preventing endwise movement of the tile with respect to the channel after the tile have been placed therein. The channel is generally designated by the numeral 65 and has a corrugated web portion 66 to which a bar 61 is welded to extend. crosswise thereof. Where metallic roofing structures are encountered, the retainer 65 may be welded Yor 40 be otherwise suitably secured thereto.

Although specific embodiments of the invention have been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention and such changes are contemplated.

What I claim is:-

1. A roofing element comprising a sheet metal body and a composition body, said metal body having a pair of spaced apart arms extending through said composition body, said arms having retainer receiving means.

2. A rooiing element comprising a sheet metal body, a composition body, said metal body having one end extended over and partially coveringone end of said composition body, and a pair of arms integral with said metal body and projecting through said composition body, said arms having retainer receiving portions in their outer faces.

3. A roof composed of roofing elements laid in overlapping relation with one edge and a portion of the upper surface of each element exposed, each roong element comprising a Wear resisting fire-proof surface body, and a composition insulating body secured to the under surface thereof, the surface body being extended over a portion of the exposed end of each roofing element with the terminal of the extendedjportion being spaced slightly from the lower surface of the insulating body whereby it protects themajor area of the said exposedend yet does not contact the surface body of the roofing element which it overlaps. Y

4. In a construction of the character described, a stationary support, a resiliently yieldable retainer means attached to said'support, roofing elements, and resiliently yieldable means on said roofing elements received in and compressed by said retainer means and retained therein by the friction induced through compression thereof, said retainer means and last named means supporting said roofing elements in overlapped relation with the overlapping ends held pressing against the roofing elements which they overlap.

5. In a construction of the character described, a stationary support disposed `at an angle with respect to a horizontal plane, resiliently yieldable retainer means attached to said support whereby itextends at an angle substantially corresponding thereto, roofing elements, resiliently yieldableameans on said roofing elements received in and compressed by said retainer means and held therein by friction induced by compressing the same, said retainer means and last named means supporting said roofing elements in overlapped relation with the overlapping ends held pressing against the roofing elements which they engage, l and positive means in said retainer means adapted to be engaged by the resilient means on the lowermost roofing element to prevent sliding thereof downwardly in said angular- 1y disposed retainer means.

6. Ina construction ofthe character described, a stationary supporting structure formed of metal, a metal channel comprised of resiliently yieldable side walls united by an integral web, said side walls having retainers thereon, said channel having its web welded to said metal supporting structure, metal roofing elements and resiliently yieldable elements integral with said roong elements, said resiliently yieldable elements being received between the walls of said channel and being compressed thereby to maintain them in engagement with the retainers thereon and supporting said roong elements with one overlapping another.

7. A roof comprising a supporting structure extending at an angle relative to a horizontal plane, a plurality of pairs of yieldably spaced apart elements attached to said supporting structure,

roofing elements, resiliently compressible means on said roofing elements received in respective sets of spaced apart elements and retained therein by resilient pressure resulting from compression by said spaced apart elements whereby they support said roofing elements overlapped, and positive, means for preventing sliding movement of the lowermost one of each series of roofing elements and through the inter-engagement of the several overlapped roong elements of each series holding the entire series against sliding movement.

8. In combination, a channel member having resiliently yieldable side walls, lengthwise tapered J roofing elements, and resiliently compressible projecting portions on said roong elements, said projecting portions extending between and compressed by said resiliently yieldable side walls and frictionally engaged therewith as a result of compression thereof to support said roofing elements with the thicker end overlapping the thinner end of the next adjacent roong element.

9. In combination, a channel member having side walls, roong elements, said roofing elements comprising sheet metal outer layers and composition inner layers, resiliently compressible projecting portions integral with the sheet metal and projecting through the composition layers, said projecting portions extending between and compressed by said side walls and vfrictionally engaged therewith as a result of compression thereof to retain said roofing elements with respect thereto.
